Scouting Report: Sem Robberse
St Louis Cardinals | SP
Overall
Summary
Robby Snelling, a top pitching prospect for the Miami Marlins (ranked 29th-33rd overall and 5th among LHP prospects), was placed on the 15-day injured list on May 14, 2026, with a UCL sprain in his left elbow just one start into his major league career. The 22-year-old made his MLB debut on May 8 against Washington, allowing 3 runs over 5 innings while walking 4 and striking out 2. He reported discomfort following a bullpen session on May 13. The severity of the injury is undetermined, but Tommy John surgery is a possibility, which could sideline him for the remainder of 2026 and potentially most of 2027. Prior to his injury, Snelling was dominant in Triple-A Jacksonville with a 1.86 ERA, 44 strikeouts, and a 3-1 record over 6 starts and 29 innings.
